Instructions for Completing Checklist This checklist may be used to document the results of the Seismic Walkdown of an item of equipment on the SWEL. The space below each of the following questions may be used to record the results of judgments and findings.

Additional space is provided at the end of this checklist for documenting other comments..

Anchoralle

1. Is the anchorage configuration verification required (i.e., is the item one Yo- NZ of the, 50% of SWEL items requiring such verification)?
2. Is the anchorage free of bent, broken, missing or loose hardware?There is one anchor missing on: the south side of the. support for Instrument Rack 2H21-P021 (CR 515727). There is a good deal of debris in. the hole, so it is unsure whether the anchor is broken off, removed or was never installed There are seven other anchors in good condition, and the rack frame is very stiff.3. Is the anchorage free of corrosion that is more than mild surface oxidation?

Instructions for Completing Checklist This checklist may be used to document the results of the Seismic Walkdown of an item of equipment on the SWEL. The space below each of the following questions may be used to record the results of judgments and findings.

Additional space is provided at the end of this checklist for documenting other comments.Anchorage 1. Is the anchorage configuration verification required (i.e., is the item one of the 50% of SWEL items requiring such verification)?

YE] NZ 2. Is the anchorage free of bent, broken, missing or loose hardware?There are four anchors of the 10 anchors that have cut washers. The cutting of these washers has no affect on the ability of these four anchors to carry the seismic loads applied to them during a seismic event. Therefore, the anchorage is seismically acceptable.

3, Is the anchorage free of corrosion that is more than mild surface oxidation?

There is mild surface corrosion on one of the anchors. SWE's determined that this is seismically acceptable due to minimal corrosion.

4, Is the anchorage free of visible cracks in the concrete near the anchors?5, Is the anchorage configuration consistent with plant documentation?(Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

The top left anchor does not have full engagement of the bolt. The end of the bolt is approximately 1/16" below the nut. The other three bolts are fully engaged 3/8" dia. anchors, and have enough capacity to support the small, light component.

Therefore, there is no potentially adverse seismic condition.

However, this is judged not be a seismic concern by SWEs since the other three spring nuts are in compression.

The unistrut is welded to the embedded wall plate. Right bottom comer bolt doesnot have a washer installed.

However this is not a seismic concern since the bolt hole is not oversized.

Instructions for Completing Checklist This checklist may be used to document the results of the Seismic Walkdown of an item of equipment on the SWEL. The space below each of the following questions may be used to record the results of judgments and.findings.

Additional space is provided at the end of this checklist for documenting other comments.Anchorage 1. Is the anchorage configuration verification required (i.e., is the item one of the 50% of SWEL items requiring such verification)?

Panels were openend per work order SNC427042.

2. Is the anchorage free of bent, broken, missing or loose hardware?3. Is the anchorage free of corrosion that is more than mild surface oxidation?
4. Is the anchorage free of visible cracks in the concrete near the anchors?5. Is the anchorage configuration consistent with plant documentation?(Note: This question only applies if the item is one of the 50% for which an anchorage configuration, verification is required.)

Anchorage verified using calculation SCNH-99-406, Rev. 0. A SEWS package dated 10/25/1988 is included within the body of the calculation.

There are fillet welds present inside the west side of the panel, northwest section. There are plug welds at the holes of the angle base of the panel. Two holes are not plug welded, which are located at the northwest section (south end of that section) and the southwest section (north end of that section).

See photograph 3.Calculation SNCH-99-406, Rev. 0 provides the SQUG evaluation for this control panel. The SQUG evaluation only takes credit for welds on the outside of the panel. The interior fillet and plug welds are not considered as part of the anchorage in the calculation.

The addition of the plug welds and interior welds only increases the capacity of the panel anchorage.

Therefore, it is consistent with the plant documentation.

There is an overhead ceiling light directly over the control panel and adjacent to raceway 2E23374. The light is properly attached at the top with wire ties. The light could potentially swing and impact the raceway, however, the raceway is rigid and the impact will not cause damage to cables within the raceway. The light is judged to not be a seismic concern.9. Do attached lines have adequate flexibility to avoid damage?Two rigid raceways (2E23374 and 2E23373) connect to cable tray 2LBA806 with adequate flexibility.

A 4" diameter RGS conduit (2E23719 and a 1" diameter RGS conduit connect to the top of the control panel and are next supported approximately 8'-O"above to a strut support. This is not viewed as a seismic concern because he available length of conduit provides adequate flexibility.
